In a method for manufacturing a sidewall member of a continuous casting mold from a copper blank, wherein the sidewall member has an upper and a lower edge and a curved widened area beginning at the upper edge and tapering in a direction to the lower edge and to the sides of the sidewall member, the copper blank is hot-forged via several intermediate shapes to a rectangular plate with an initial wedge shape. The rectangular plate is then further formed by final hot-forging in a longitudinal direction of the rectangular plate with a straight saddle, having a width that is only a portion of a width of the rectangular plate measured relative to the longitudinal direction of the rectangular plate, and the curved widened area is preforged. Subsequently, the rectangular plate is quenched and work-hardened. The rectangular plate is then cold-hammered via a wedge-shaped bottom saddle for work-hardening a middle portion of the rectangular plate and for producing a final wedge shape of the rectangular plate. Finally, the entire curved widened area is work-hardened with a narrow saddle.
Dans une méthode de fabrication d'une paroi latérale de moule pour coulée continue à partir d'une ébauche en cuivre où la paroi latérale est dotée d'un bord supérieur et inférieur et d'une zone bombée en évasement commençant au niveau du bord supérieur et taraudée en direction du bord inférieur et des côtés de la paroi latérale; l'ébauche en cuivre est forgée à chaud, en passant par plusieurs formats intermédiaires, en une plaque rectangulaire avec une forme en coin initiale. Au cours d'une opération terminale de forge à chaud, la plaque rectangulaire est encore transformée dans son sens longitudinal à l'aide d'une selle droite dont la largeur ne représente qu'une partie de la dimension en largeur de la plaque rectangulaire par rapport à son sens longitudinal et que la zone bombée en évasement est alors déjà formée partiellement. La plaque rectangulaire est ensuite trempée et consolidée à froid. Elle est ensuite martelée à froid à l'aide d'une selle inférieure en forme de coin pour la consolidation à froid de la zone centrale de la plaque rectangulaire et pour créer le format final en forme de coin de la plaque. Enfin, l'ensemble de la zone bombée en évasement est consolidée à froid à l'aide d'une selle étroite.
